PhysX Bind - but not between elements

[CLF73]

   

I have a few square tiles placed in a row.
I break them up with Voronoi into smaller pieces, and have them knocked down with a collision.

How do I make sure that the PhysX bind operator doesn't bind across the the individual tiles, and only bind within the tile (element)?
Thank you

Few ways...
Here's one...
Add custom property above voronoi, with float Birth ID.
Then in the PhysX Bind, turn on clustering with that float value.

Attaching you quick example file... turn on and off clustering in the PhysX Bind, and you will see that it works.

Makes sense. 
Thank you for your reply.
